dixiedog Posted April 11, 2006 Posted April 11, 2006 Hey everyone, I tried coating some iron filings from brake rotor turnings with linseed oil. The results after drying was sticky lumpy clumps of filings. I tried breaking them up in various ways, but still somewhat lumpy. What I think I read was to put them in a pan and kinda stir fry them until they turn almost black. I used a small boiler and threw in about a cup of filings with about couple of ounces of oil, Then heated while stirring. It smoked a lot. After drying,The filings stuck to each other in a gummy fashion. Could someone clear me up on this? Did I use to much heat? Thanks
Mumbles Posted April 11, 2006 Posted April 11, 2006 You probably used too much linseed oil. Also, they may not be dry yet. It should not stick when it is dry. I have never actually heard of heatng the oil. Usually it is coated and allowed to dry on it's own. There is a product called "Japan Drier" that catalyses the polymersation and drying of the linseed oil. Did you use raw linseed oil, or boiled linseed oil? You need to use boiled I think.
asilentbob Posted April 13, 2006 Posted April 13, 2006 I have some brake rotor turnings/shavings too, but i have kept them sealed up pretty well and they look to have a black coating of some kind already on them. Mabey some kind of oil. I don't know for sure as my friend collected them for me when he had a job at an auto shop. I'm not sure if they use stainless steel often, if they do, i may have that as i can't see any rust on them.
